Improvement of process control and refractory performance of the AOD converter

Objectif

This project has the aims to improve and to extend the process observation and control system from a nearly terminated ECSC project on AOD converter control, as well as to extend and to apply refractory wear modelling from an earlier ECSC project on refractory performance in the AOD converter. The optimal time for switching the inert gas from nitrogen to more expensive argon shall be determined by on-line simulation of nitrogen pick-up and prediction of subsequent denitrogenation, in order to decrease the argon consumption and to adjust the final steel nitrogen content more accurately. The knowledge of the development of different kinds of refractory wear in the converter will allow to build a model which enables to find the best set of refractory materials and to define converter operating practices with reduced refractory consumption.
